1 Brug sidefod under VIS 5th Annual Microturbine Applications Workshop Ottawa, Canada – January 25 – 27, 2005 European experiences with 18 Microturbines "the OMES project" presented by: Aksel Hauge Pedersen Dansk Olie og Naturgas A/S Denmark

2 Brug sidefod under VIS OMES – Optimized Microturbine Energy Systems (http://www.omes-eu.com)

3 Brug sidefod under VIS OMES - Content Demonstration of 18 - 100 kW e - microturbines in Norway, Sweden, Finland, Denmark, Germany and Ireland. Development of microturbine solutions for CHP, cooling and industrial processes. Development of microturbine solutions for different fuels (natural gas, biogas and methanol) Different applications èCHP production èCluster plant - power production èSteam production èCooling èCO 2 in green houses Alternative fuels (to natural gas) è Biogas è Methanol

4 Brug sidefod under VIS OMES - Targets Energy efficient and flexible microturbine solutions Realistic data for efficiency, environmental conditions, O/M conditions etc. National-/EU possibilities for CO 2 reduction Enforce EU position in the global market for microturbines Technology Targets èPower efficiency from 30 to 33%, and in the long run to 40% èAvailability > 90% èFuel flexibel (Natural gas, Biogas, LPG, Diesel) and in the long run to handle fuels with heating values down to 25% of the heating value for natural gas. èNO x < 15 ppm at 15% O 2,. èMaintenance costs < 12,5 USD/MWh

11 Brug sidefod under VIS Did we reach the success criteria for the OMES project? Success Criteria for the OMES projectAchivements Power Efficiency 30 % during full load operation (ref. LCV) OK for the newest versions installed. The first installations had power efficiencies between 29- and 30%. Overall efficiency 85 % (ref. LCV) Not achieved. The major problems seems to be heat loos through ventilation air, and to high inlet water temp. Observed interval for for overall efficiency 60 - 80%, primarily depending of inlet water temperature. Availability 90 % OK for most installations O/M Costs < 12,5 USD /MWh e.Not achieved. Observed results 16 – 18,5 USD/MWh Unit Cost < 1000 USD/kW e OK? Observed result: 1000 – 1075 USD/kW Emission levels < 15 ppm NO x, @ 15% OAlmost OK for most sites at full load and part load. For CO and UHC - levels < 10 ppm @ 15% O 2 were achieved at full load, but raising levels found at low load conditions.

18 Brug sidefod under VIS Conclusions from the OMES project z Most technical and environmental goals were achieved, and unit cost seems OK z Remaining problems with economic parameters like overall efficiency, O/M costs - and installation costs: Overall efficiency is very dependent of inlet water temperature, which carefully must be taken into account by planning new installations. O/M costs are likely to be reduced as the number of micro turbines increase. Installation costs variation 800 - 2000 USD/kW. 125 – 375 USD/kW, was OMES specific costs (measurement, data transmission etc.). The observed level will be reduced when "plug and play" micro turbine installations can be made, and/or authorities will be accustomed to the micro turbine installations. The OMES project showed that the micro turbine technology is reliable and working satisfactory. Installation costs must be reduced to give the micro turbine a commercial break through.
